A Comparison of Autism Prevalence Trends in Denmark and Western Australia / Erik T. PARNER in Journal of Autism and Developmental Disorders, 41-12 (December 2011)
[article]
Titre : A Comparison of Autism Prevalence Trends in Denmark and Western Australia Type de document : Texte imprimé et/ou numérique Auteurs : Erik T. PARNER, Auteur ; Poul THORSEN, Auteur ; Glenys DIXON, Auteur ; Nicholas H. DE KLERK, Auteur ; Helen LEONARD, Auteur ; Natasha NASSAR, Auteur ; Jenny BOURKE, Auteur ; Carol BOWER, Auteur ; Emma J. GLASSON, Auteur Année de publication : 2011 Article en page(s) : p.1601-1608 Langues : Anglais (eng) Mots-clés : Autism Autism spectrum disorders Prevalence Diagnosis Denmark Western Australia Index. décimale : PER Périodiques Résumé : Prevalence statistics for autism spectrum disorders (ASD) vary widely across geographical boundaries. Some variation can be explained by diagnostic methods, case ascertainment and age at diagnosis. This study compared prevalence statistics for two distinct geographical regions, Denmark and Western Australia, both of which have had population-based registers and consistent classification systems operating over the past decade. Overall ASD prevalence rates were higher in Denmark (68.5 per 10,000 children) compared with Western Australia (51.0 per 10,000 children), while the diagnosis of childhood autism was more prevalent in Western Australia (39.3 per 10,000 children) compared with Denmark (21.8 per 10,000 children). These differences are probably caused by local phenomena affecting case ascertainment but influence from biological or geographical factors may exist.

Titre : Parental socioeconomic position and risk of autism spectrum disorders in offspring: A cohort study of 9,648 individuals in Denmark 1976-2013 Type de document : Texte imprimé et/ou numérique Auteurs : Emilie Rune HEGELUND, Auteur ; Trine FLENSBORG-MADSEN, Auteur ; Ditte VASSARD, Auteur ; Leonard A. ROSENBLUM, Auteur ; June Machover REINISCH, Auteur ; Erik Lykke MORTENSEN, Auteur Article en page(s) : p.1-8 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Socioeconomic factors Cohort studies Denmark Index. décimale : PER Périodiques Résumé : Background The results of studies of the association between parental socioeconomic position (SEP) and risk of autism spectrum disorder (ASD) in offspring are inconsistent, perhaps due to contextual differences in health care systems and their influence on risk of ASD diagnosis among different socioeconomic groups. The present study investigated the association between parental SEP in adulthood and risk of ASD diagnosis in offspring in a Nordic welfare state and whether this association was modified by parental childhood SEP. Method The study population comprised 9648 live-born singletons who were followed in the Psychiatric Central Register from birth in 1976–1996 until 2013. Cox regression was used to estimate hazard ratios for ASD diagnosis according to parental SEP in adulthood. Results The crude results showed a tendency towards higher parental SEP in adulthood being associated with higher risk of ASD diagnosis in offspring. However, the association was reversed after adjustment for possible confounders. The reversion of the direction of the association was entirely attributable to the strong confounding effect of calendar year. Further, the results showed that parental childhood SEP modified the association between parental SEP in adulthood and risk of ASD diagnosis in offspring. Conclusions Both methodological and contextual issues may be of great importance for the observed association between parental SEP and risk of ASD diagnosis in offspring. Particularly, the secular trends in ASD diagnoses seem to be of great importance suggesting that changes in diagnostic patterns may influence the association between parental SEP and risk of being diagnosed with ASD.

Children and adolescents who already live with a mental illness may be particularly vulnerable to the distress associated with the pandemic - due to, for example, fear of the virus as well as the significant societal changes launched to minimize spread of the virus (social distancing and quarantine). In this editorial perspective, we (a) provide data on COVID-19 pandemic-related psychopathology in children and adolescents from a large psychiatric treatment setting in Denmark, (b) give advice on how the likely harmful effects of the COVID-19 pandemic on the mental health of children and adolescents may be minimized, and (c) propose six lines of research into pandemic-related psychopathology with emphasis on children and adolescents. Finally, we underline the necessity of politicians, health authorities, and funding bodies supporting these research initiatives here and now.

Titre : Toward a cumulative science of vocal markers of autism: A cross-linguistic meta-analysis-based investigation of acoustic markers in American and Danish autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Riccardo FUSAROLI, Auteur ; Ruth GROSSMAN, Auteur ; Niels BILENBERG, Auteur ; Cathriona CANTIO, Auteur ; Jens Richardt MØLLEGAARD JEPSEN, Auteur ; Ethan WEED, Auteur Article en page(s) : p.653-664 Langues : Anglais (eng) Mots-clés : Acoustics Adolescent Autism Spectrum Disorder/diagnosis Autistic Disorder Biomarkers Child Denmark Humans Language Linguistics autism spectrum disorder cross-linguistic speech voice Index. décimale : PER Périodiques Résumé : Acoustic atypicalities in speech production are argued to be potential markers of clinical features in autism spectrum disorder (ASD). A recent meta-analysis highlighted shortcomings in the field, in particular small sample sizes and study heterogeneity. We showcase a cumulative (i.e., explicitly building on previous studies both conceptually and statistically) yet self-correcting (i.e., critically assessing the impact of cumulative statistical techniques) approach to prosody in ASD to overcome these issues. We relied on the recommendations contained in the meta-analysis to build and analyze a cross-linguistic corpus of multiple speech productions in 77 autistic and 72 neurotypical children and adolescents (>1000 recordings in Danish and US English). We used meta-analytically informed and skeptical priors, with informed priors leading to more generalizable inference. We replicated findings of a minimal cross-linguistically reliable distinctive acoustic profile for ASD (higher pitch and longer pauses) with moderate effect sizes. We identified novel reliable differences between the two groups for normalized amplitude quotient, maxima dispersion quotient, and creakiness. However, the differences were small, and there is likely no one acoustic profile characterizing all autistic individuals. We identified reliable relations of acoustic features with individual differences (age, gender), and clinical features (speech rate and ADOS sub-scores). Besides cumulatively building our understanding of acoustic atypicalities in ASD, the study shows how to use systematic reviews and meta-analyses to guide the design and analysis of follow-up studies. We indicate future directions: larger and more diverse cross-linguistic datasets, focus on heterogeneity, self-critical cumulative approaches, and open science. LAY SUMMARY: Autistic individuals are reported to speak in distinctive ways. Distinctive vocal production can affect social interactions and social development and could represent a noninvasive way to support the assessment of autism spectrum disorder (ASD). We systematically checked whether acoustic atypicalities highlighted in previous articles could be actually found across multiple recordings and two languages. We find a minimal acoustic profile of ASD: higher pitch, longer pauses, increased hoarseness and creakiness of the voice. However, there is much individual variability (by age, sex, language, and clinical characteristics). This suggests that the search for one common "autistic voice" might be naive and more fine-grained approaches are needed.
